While the special for this series had me trying to figure out the series the comments left for that review were encouraging that the TV series would be a more fulfilling watch. And so far that is proving to be true.
Overall though this episode is strong with a good mystery that has rather high tension in the fact that lives were on the line instead of the usual murder mystery set up where the only death is before the mystery solvers come into play. And like I mentioned before there is a larger mystery that comes into play as well in the episode that thankfully adds to the story instead of distracts.
It is probably good advice that even if you did not like the SP to still give the first episode of this series a try. The TV series looks like it will be much stronger and more enjoyable if you like mystery series.
